我对java知之甚少。 我可以使用jsoup获取java代码来提取数据并重新运行下面的outpu吗

实际上，这个数据是一个样本数据。我这里没有提到带有html标记的数据。

由于信息在
标记之间划分，您必须选择所有这些标记，并逐个打印它们的文本，假设AUDIT\u SCOPE\u LOB是有效的Java
字符串
：

Document doc = Jsoup.parse(AUDIT_SCOPE_LOB);
    Elements el = doc.select("p");
    for (Element e : el) {
        System.out.println(e.text());
    }

org.jsoup.nodes.Element.toString（）
返回

获取此节点的外部HTML


获取此元素及其所有子元素的组合文本。 空白被规范化和修剪


因此，对整个示例调用
toString（）
将返回与输出相同的结果。同样，调用
text（）
将以单个字符串的形式返回所有不带标记的文本。但是，您需要的是每个文本段落的单个字符串

您的某些段落标记为空。为了获得示例中的输出，您应该首先验证每个段落是否有文本

Document doc = Jsoup.parse(AUDIT_SCOPE_LOB, "UTF-8");

for (Element p : doc.select("p"))
    if (p.hasText())
        System.out.println(p.text());
输出

Start: 8:30 am
End: 4 pm

查看更多有关如何解析数据的示例。例如，如果要解析出有序列表，可以在类名上选择并检索列表中的第二个跨度

for (Element span : doc.select("p.MsoNormal > span:nth-child(2)")) 
     System.out.println(span.ownText());
输出

“我可以使用jsoup获取java代码来提取数据并重新运行输出，如下图所示”
——是的，但该代码的第一个源代码应该是您和您的尝试。这不是一个“请给我代码”类型的网站，而是一个问答网站。您需要学习JSoup教程，学习Java和JSoup，然后在提问之前至少尝试一个解决方案，然后通过提问展示您的尝试。这将允许你提出一个更具体、更负责任的问题。Luck.BTW，当我指的是展示你的尝试时，我指的是一次真正的尝试，一次表明你已经学习了教程的尝试，比你在上面发布的代码行更加充实。@HovercraftFullOfEels-我认为OP确实展示了解决他问题的真正尝试。如果AUDIT_SCOPE_LOB是一个字符串，那么应用这两次尝试确实给出了他提供的输出，这就是我回答他的原因。@Hovercrft充满了鳗鱼谢谢你的时间。事实上，我是一个信息资源。在为那个html问题寻找解决方案之后，我听到了Jsoup这个名字。然后我导入了Jsoup jar文件并尝试了一些东西。即使我没有像Eclipse这样的环境来编写Java代码和测试。像标记“p”，我必须处理所有的标记r8？我不知道什么是r8标记，但是如果它的结构像p标记，那么是的。在像“p”这样的问题中，我必须处理所有的标记？
